Half-life (t1⁄2) is the amount of time required for the amount of something to fall to half its initial value. For a specific amount of time, we'd need a specific substance.
1/2 = 0.5 = 5 x 10^-1

If half lives is 1 and time elasped is 1620 year what is mass remaining?
Half life has unit. That is unit of time. So it has to be mentioned. Let us assume that half life is 1 year. Okay. Now to know about the mass remaining we have to get the ratio (1/2)^1620. Hence remaining will be 1/(2^1620) * mass at the beginning
The time it takes for half of the radioactive element to decay is the element's what?
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
What is the term given to the time it take for one half of a sample of radioactive nuclei to decay?
I believe that term would be 'half-life'
What does half life of a pill mean?
A "Half-Life" is not half of a life, it is half of the life, then half of that life, and then half of THAT life, and so on and so on. For example: Rock has a half life of 100 ---> 50 ---> 25 ---> 12.5 ---> 6.25 ---> and so on. You just keep dividing the life it has, by 2. Another Example: If you take a dissolving vitamin, and weigh it (20g), and put it in water for 1 minute, it should dissolve into ALMOST half of its original weight, into 10g. Scientists often use the method of "Half-Life" to measure the age of a rock or rock formation. Sources: Am a student in science class
How long will it take half of a radioactive sample to decay?
The length of time depends on the element and isotope, but the point at which half of the sample has decayed is known as the half-life.

In chemistry what is a half life?
The half-life of a quantity whose value decreases with time is the interval required for the quantity to decay to half of its initial value. The concept originated in describing how long it takes atoms to undergo radioactive decay but also applies in a wide variety of other situations.Half-lives are very often used to describe quantities undergoing exponential decay-for example radioactive decay-where the half-life is constant over the whole life of the decay, and is a characteristic unit (a natural unit of scale) for the exponential decay equation. However, a half-life can also be defined for non-exponential decay processes, although in these cases the half-life varies throughout the decay process. The converse for exponential growth is the doubling time.
What is the unit of life for a tree and a human respectively?
In the family tree, the unit of life is genes.
What is the The fundamental unit of life?
Cells are the fundamental unit of life.
What is the fundamental unit of life?
Cells are the fundamental unit of life.
What is the price of half and half?
It is 1.5 times the unit price.
Does Half life opposing force require Half life?
No. Half Life: Opposing Force does not require neither Half Life nor Half Life: Blue Shift.
The time it takes for half of the radioactive element to decay is the element's what?
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
What is curie half life?
Half-life depends on the particular nuclide involved. You did not specify which nuclide. Please restate the question. Curie is a unit of radioactivity, expressed as 3.7x1010 disintegrations per second. It is not a radionuclide. If you meant curium, you still need to specify which isotope, because curium has several. The longest lived isotope of curium is 96247Cm, with a half-life of 1.56x107 years.
What is the term given to the time it take for one half of a sample of radioactive nuclei to decay?
I believe that term would be 'half-life'
Is there more blood in half life or Half Life Source?
Most likely Half Life Source
